At the Battle Tree, challengers compete to see how many Trainers they can defeat in a row. Losing one battle will reset the challenger's win streak to zero. Each time a challenger defeats a Trainer, Battle Points, or BP, will be awarded. The longer the win streak, the more BP will be received.
There are three formats a challenger can choose: Single Battle, Double Battle, or Multi Battle. The challenger needs three Pokémon for Single Battles, four for Double Battles, and for Multi Battles, two per Trainer. Lastly, challengers cannot use more than one of the same Pokémon or item. However, this does not restrict Multi Battle partners from using the same Pokémon or item across teams.
There are two courses for each format: Normal Course and Super Course. A Normal Course challenge consists of 20 battles, the last of which will be against a Battle Legend. Upon successfully completing a Normal Course, the Super Course for the respective format will be unlocked, in which the challenger may rebattle the same Battle Legend on the 50th battle. Unlike the Normal Course, the Super Course is indefinite and ends only when the challenger loses a battle.
All NPC Trainers in the Battle Tree use Pokémon from a list of 996 Pokémon and moveset combinations. Each of their Pokémon has a fixed Nature and EV spread for effort values. IVs are equal across all stats and based on the Trainer using it. The gender and Ability are randomly selected each battle. Each Trainer will use two to four Pokémon, depending on the format selected.
In Pokémon Sun and Moon, both courses prohibit certain species Pokémon and are held under Flat Rules - any Pokémon higher than Lv. 50 will have their level lowered to 50. In Pokémon Ultra Sun and Ultra Moon, the level and special Pokémon restrictions are lifted for the Normal Courses, while the opponents' Pokémon are still fixed at Lv. 50.

The following Pokémon species and their forms are banned from challenges that ban special Pokémon. Eggs cannot be used in any battle.
Like in the Battle Maison, the player receives Battle Points (BP) at the end of every victorious match. The number of Battle Points (BP) awarded after a match varies with the length of the current win streak, as shown in the table below.
20 (Battle Legend)
50 (Battle Legend)
On the 20th battle of normal challenges and the 50th battle of Super challenges, a Battle Legend will be challenged. Red is the Battle Legend for Single Battle challenges, using three Pokémon each time. Blue is the Battle Legend for Double Battles and uses four Pokémon. For Multi Battles, both Battle Legends will appear simultaneously, each using two Pokémon. Upon defeating the Battle Legend, the Pokémon used in that battle will be awarded a Battle Tree Great Ribbon or Battle Tree Master Ribbon for normal or Super mode, respectively.

Multi Battle partners
In the Multi Battle and Super Multi Battle challenges, the player can choose to partner with a friend or with the AI. Unlike the Battle Maison from previous generations, there is only one default AI partner, Pokémon Breeder Rada. To increase the number of AI partners available, the player must Scout opponents after defeating them in Single or Double Battles. Scouting a Trainer costs 10 BP, and this will add the Trainer to the list of potential AI partners. When a Trainer is scouted, the first two Pokémon of their team will be the Pokémon they use in Multi Battles, and they are sent out to battle in the same order as well. If a Trainer who has already been recruited is scouted again, then the new team will override the old one. Battle Legends cannot be scouted, but the other special Trainers can be recruited. Scouted trainers' Pokémon will retain the same randomly-chosen abilities they had from the battle they were scouted in, but will always become male except in the case of a female-only or genderless species.
Next to the PC, the player can find a male Ace Trainer, who is supposed to judge the IVs of the player's lead Pokémon. However, unlike the judges in the previous games, he's unwilling to judge the player's Pokémon. If the player has hatched at least 21 Eggs, the judge will update the player's PC with a feature that allows them to view the IVs of their Pokémon themselves, after which he leaves.
Upon entering the Battle Tree area for the first time, the player will encounter Red and Blue, and have a battle against one of them. The player gets to choose which one of the two they want to battle. In Pokémon Ultra Sun and Ultra Moon only, Blue will heal the player's Pokémon before the battle.
